FIELD OF THE EMBODIMENTS

The invention and its embodiments relate to a ventilated shoe, in particular a ventilated shoe capable of pumping air throughout itself.

BACKGROUND OF THE EMBODIMENTS

A user's comfort, with regard to heat, is affected by heat conduction, convection, radiation, and evaporative heat loss. A comfortable temperature is maintained when the heat generated by a human's metabolism is allowed to dissipate, thus maintaining thermal equilibrium with the surroundings. It has been long recognized that the sensation of feeling hot or cold is not just dependent on air temperature alone. Very hot or cold weather can cause individuals extreme discomfort and create a sense of suffering when adequate protection against the environment is absent. Further, perspiration from the body is used to cool down a user, provided that the user's clothing and conditions permit the evaporation of the perspiration. Contrapositively, the same person at the same temperature may feel extremely uncomfortable when conditions prevent the evaporation of perspiration. The proper clothing can make all the difference; however many items of clothing do not take perspiration into account.

One article of clothing, the shoes, may provide the least amount of adjustment for comfort of the wearer. Activities generally dictate the type of shoe that needs to be worn, whether for formal occasions or for sports. Regardless of the type of shoe worn by an individual, the feet can become hot and uncomfortable in warm weather. The interior of shoes also tend to become moist and warm in warm weather, the ideal condition for fungus growth. While some people are more prone to fungus growth such as Athlete's Foot, than others, foot sweating and discomfort is something that all people feel frequently. Athlete's foot (also known as ringworm of the foot and tinea pedis) is a fungal infection of the skin that causes scaling, flaking, and itch of affected areas. It is caused by fungi in the genus Trichophyton. While it is typically transmitted in moist communal areas where people walk barefoot, such as showers or bathhouses, the disease requires a warm moist environment, such as the inside of a shoe, in order to incubate. The reason the insides of shoes have favorable conditions for the proliferation of Athlete's foot is because of the lack of ventilation inherent in most shoe designs. Even cloth shoes, such as tennis shoes, tend to prevent adequate air movement for many individuals. Wearing open shoes such as sandals can allow air flow and help considerably; however they do not provide adequate protection against injury from foreign objects or from thermal extremes. A solution for ventilating all types of shoes is desirable.

Ideally, ventilated shoes should provide comfort and cooling, yet would operate reliably and be manufactured at a modest expense. Thus, a need exists for a reliable pumped air cooling shoe system to cool and dry the feet of the wearer during use, and to avoid the above-mentioned problems.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

The preferred embodiments of the present invention will now be described with reference to the drawings. Identical elements in the various figures are identified with the same reference numerals.

Reference will now be made in detail to each embodiment of the present invention. Such embodiments are provided by way of explanation of the present invention, which is not intended to be limited thereto. In fact, those of ordinary skill in the art may appreciate upon reading the present specification and viewing the present drawings that various modifications and variations can be made thereto.

As discussed above, embodiments of the present invention relate to a ventilated footwear device and more particularly to a pumped air cooling shoe system as used to improve the cooling and drying the feet of the user-wearer at an affordable cost.

Generally speaking, the present invention provides for a ventilating shoe for cooling and drying the feet of a user. In a preferred embodiment, the present invention utilizes a pump located in the heel of a shoe. The pump resides in an air-impermeable cavity.

Referring to FIG. 1, the cooling shoe of the present invention is shown. Here, the cooling shoe comprises pump 105, spring cover 110, spring 115, at least one inlet check valve 120, containment box 130, inner volume 135, at least one tube 140, at least one perforation 145, at least one intake 150, at least one outlet 155, and shoe 160. Preferably, the at least one intake 150 will be located at the top of a user's shoe. This prevents debris close to the ground from getting sucked into the system. Further, it is important to balance the surface area of at least one intake 150 and at least one outlet 155 so that a sufficient velocity of air is pushed through the system. The actual size of at least one intake 150 and at least one outlet 150 is not as important and their respective sizes, due to Bernoulli's equation which shows that the velocity of any fluid (including air) in a system such as this is directly related to the area differential upon which the fluid is traveling through. At least one perforation 145 provides for additional cooling and ventilation. This dual-action ventilation is featured in a number of preferred embodiments.

Referring to FIG. 2, integratable cooling system 100 is provided. Here, integratable cooling system 100 is comprised of spring 115, spring cover 110, at least one inlet check valve 120, at least one outlet check valve 125, containment box 130, inner volume 135, at least one tube 140, at least one intake 150, and at least one outlet 155. This embodiment shows a system that can be incorporated into almost any item of footwear. In one embodiment, containment box 130 is located under the heel of a user. In an alternative embodiment, containment box 130 is located under the ball of a user's foot. In yet another embodiment, the user may choose where they located the containment box, provided that it is compressed when the user takes a step. While at least one outlet 155 can be located anywhere, it is preferably located at the front of a user's foot. With the increased surface area of the toes, the cool air blowing over them will be most effective at cooling down the user.

Referring to FIG. 3, a flow chart showing an embodiment of the method of the present invention is shown. Here, the method starts out with step 205, where a cooling shoe similar to what is depicted in FIG. 1 is provided. A user then steps on the containment box located in said shoe in step 210. In step 215, this step results in the pump being depressed. This results in step 220 where the pump forces air to be sent through the at least one outlet check valve, through the tube and out the at least one outlet contained in said shoe. After this process is complete, a user then removes their body weight from the containment box in step 225, allowing the spring to force the containment box to return to its natural resting position in step 230. Step 230 causes the importation of air through the tube such that the inner volume of said containment box becomes filled with air in step 235.

In a preferred embodiment, springs of various stiffness can be used to accommodate users of various weights. Additionally, many embodiments feature a spring bumper guard, which is located inside of the spring of the present invention, and is sized to prevent the complete compression of this spring. The present invention may also feature additional tubes leading both too and from the containment box, to allow for a greater volume of air to pass through the present invention. In some embodiments, the spring bumper guard is disposed on the bottom of said shoe, however, it may be suspended within the spring of the present invention as well. In a preferred embodiment, the sealing area of the present invention is constructed substantially out of rubber. In another preferred embodiment, the pump of the present invention contains a scented agent.
